The following code example demonstrates how to construct a bitmap from a type, and how to use the Save method. To run this example, paste the code into a Windows Form. Handle the form’s Paint event, and call the ConstructFromResourceSaveAsGif method, passing e as PaintEventArgs

private void ConstructFromResourceSaveAsGif(PaintEventArgs e)
{

    // Construct a bitmap from the button image resource.
    Bitmap bmp1 = new Bitmap(typeof(Button), "Button.bmp");

    // Save the image as a GIF.
    bmp1.Save("c:\\button.gif", System.Drawing.Imaging.ImageFormat.Gif);

    // Construct a new image from the GIF file.
    Bitmap bmp2 = new Bitmap("c:\\button.gif");

    // Draw the two images.
    e.Graphics.DrawImage(bmp1, new Point(10, 10));
    e.Graphics.DrawImage(bmp2, new Point(10, 40));

    // Dispose of the image files.
    bmp1.Dispose();
    bmp2.Dispose();
}

private void ConstructFromResourceSaveAsGif(PaintEventArgs e)
{
    // Construct a bitmap from the button image resource.
    Bitmap bmp1 = new Bitmap(Button.class.ToType(), "Button.bmp");
    // Save the image as a GIF.
    bmp1.Save("c:\\button.gif", System.Drawing.Imaging.ImageFormat.get_Gif());
    // Construct a new image from the GIF file.
    Bitmap bmp2 = new Bitmap("c:\\button.gif");
    // Draw the two images.
    e.get_Graphics().DrawImage(bmp1, new Point(10, 10));
    e.get_Graphics().DrawImage(bmp2, new Point(10, 40));
    // Dispose of the image files.
    bmp1.Dispose();
    bmp2.Dispose();
} //ConstructFromResourceSaveAsGif
